SPECIFICATION forming part of Letters Patent No. 605,442, dated June 7, 1898.

Application fi1 d January 25, 1898. Serial No. 667,846. (No model.)

To all whom it may concern:

Be it known that I, FRIEDRICH WVILHELM GUSTAV BRUHN, a subject of the German Emperor, and a resident of Berlin, in the German Empire, have invented certain new and useful Improvements in Fare Indicating and Registering Apparatus for Cabs, Carriages, and the Like, of which the followingis a specification.

This invention relates to improvements in fare indicating and registering apparatus for cabs, carriages, and the like; and the objects of the same are means for insuring the relative blocking between the mechanism which serves to indicate whether the carriage is vacant or engaged and those devices by which the fare-indicator is adjusted to various tariffs applying to trips or journeys to be paid for according to distance or time and the like or such devices which indicate any additional fee to be paid for conveying luggage or for rendering similar special services, the.

On fare-indicators a signal device, usually presenting the shape of a flag, is provided, from the position of which the public, the controlling police officials, &c., are enabled to see at a distance whether the carriage is engaged or not; also, an engaging and disengaging device by means of which the apparatus is adjusted to the various tarifis or brought into the position indicating the termination of the journey or trip. Nowin order to prevent the driver of the carriage from either cheating the passenger or defrauding the proprietor of the vehicle, or both, the signal device and the engaging and disengaging mechanism are brought into' such relative connection that the one device can only be moved when the other device occupies a certain given position, and vice versa. Both devices are, in other Words, to block each other, and this mutual blocking action being such as to admit of its being suspended only in case where both devices occupy quite a definite relative position. Moreover, frequently a particular supplementary registering device is arranged by which the driver is intended to indicate the fees for conveying luggage or the like; also, this latter device may be connected with the signal device or with the engaging or disengaging mechanism, or

with both, in such a manner that the said supplementary registering device may only be actuated when occupying absolutely definite positions.

In order to make myinvention more clearly understood,l have described it with reference to the accompanying drawings, in which Figure 1 is an elevation of the engaging and disengaging mechanism, the supplementary registering device,and the signal device in the position when the carriage is engaged; and Fig. 2, the same elevation of the like parts when the carriage is not engaged.

Similar letters refer to similar parts in both figures.

a is the signal device, in most cases in the shape of'a flag. In Fig. 1 this signal device a is shown turned down, thus indicating that the carriage is engaged, while in Fig. 2 the sameis shown standing upright, so that an inscription Free or Vacant or the like is clearly visible. at is mounted on the shaft to, upon which two non-circular disks or cams b and c, placed side by side and rigidly connected with the shaft to, are provided.

The lower shaft 6, by means of which the apparatus is adjusted to various tariffs or thrown out of engagement, carries three noncircular disks or cams. In the plane of the disk 0 of the upper shaft a lies the disk 6, in the plane of disk Z) the disk cl, and upon the latter the cam f.

The disk c has a projecting nose c for which a notch is provided in the otherwise circular disk 0, and it is only in case that this notch and the nose e engage that the signalindicator a can be turned from its engaged,

Fig. 1, to its disengaged position, Fig. 2.

The disk I) is provided withseveral notches, into which fit the several projections of disk d. The latter,moreover,possesses two notches for receiving the projections of disk I). The movement of the shaft a, as well as the rotation of the shaft 6, are thus made interdependent upon the respective positions of the disks 0 and e and b and d.

Moreover, for specially fixing the signal device a in its upright or disengaged position is provided a cam f, which is elastically connected with the shaft 6 by means of the sprin g f and the disk (1, and a pin 1) of disk I) is adapted to slide upward, Fig. 2, While yield ing to the tendency of the springf, whereby (t held in its upright position. Thus the signal device (6 cannot be turned down until the shaft c has been moved forward (in the direction of the arrow) to such an extent that the cainf is brought out of contact with. the pin h.

For blocking the disk g, which actnatcs the supplementary registering device, a lever 7; Z is arranged, which is displaced by means of a catch i, provided on disk 7): The lever 71 Z is moved into such a position with respect to the pawl hot disk g that the latter cannot be rotated in the position indicated in Fig. 2.

Having now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, I claiin- 1. in a [are indicating and registering apparatus for cabs, carriages and the like, the combination of the signal device a, the shaft (1", the disks 7) and c, with the shaft (2' and disks c and (I, substantially as and for the purpose specified.

2. in a fare indicating and registering apparaius for cabs, carriages and the like, the combination of the signal device a, the shaft 0, the disk Z1 and pin 7), with the shaft 0,

disk (Z, cam f and spring snbstai'itiai'ly as A and for the purpose specified.

in a are indicating and registering apparatus for cabs, carriages and the like, the combination of the signal device a, shaft (4',

disk I) and catch '1', with the lever 75 Z, pawl l-ltllihltltil iilllllliiibi hili'iii. iilIUIIN.
